A leak-tight seal is formed by sandwiching a metal gasket (20) between opposing annular ridges (14) surrounding the port (12) to be sealed.

The invention relates to a sealing arrangement which comprises at least two abutting components that form a gap therebetween and a seal (1) that sealingly bridges said gap.

A process and apparatus for forming a leak proof body (16) and cap (18).

Pressure to create sealing interaction of the valve parts (12, 13) is achieved with the aid of a spring arrangement (35).

A duo-cone seal assembly (300) is positioned between the hub (120) and the shaft (110) to seal out contaminants from the sleeve bearing system (200).

Thus, the electrical sealing arrangement is completely separate and different from the optical sealing arrangement.

In one embodiment, the liquid sterilant solution is vaporized by irradiating the gas-tight assembly with microwave irradiation.

Methods and related systems are described relating to a sealed acoustic transducer assembly for use in a wellbore is provided.

The gas-tight assembly is situated in an inner rigid cavity (26a) of an enclosure which is at least partially formed of material that is substantially transparent to microwave radiation.

A gas-proof assembly is obtained by applying an adhesive bead (7) on the outer periphery of the gas chamber and around the inner gas ducts.

A valve having an axial port (96) connected to a side port (90) by a path independent of a path connecting two additional side ports (88, 92).

Electrical or electromagnetic stimulation can be provided to heat the strip (54) and bond each cable (45) and the body portions (16, 18) into a sealed unit.

The pump assembly contains a sealed fluid.

A two-piece seal vial assem bly (100).

A magnetic waterproof switch assembly comprises a waterproof housing (13).
